To all whom it may concern.'

Be it known that I, "VlLHEmiUs ADRIANUS vAN' BERKEL, a. subject of the Queen of the Netherlands, and a resident of Rotterdam,

'invented certain new and useful Improvements in Machines for Slicing 'German Sausages and the Like, of which the following is a specification. Y

This invention has for its object a machine for slicing German' sausages andthe like meat goods in which a fixed, but constantly rotating circular knife of spherical' orf dished' form is arranged for. cutting the sausages.

The lengths of cutting bythe circular knife are determined by its speed of rotation andl are larger according as the speed spondingto the meat goods to be sliced'or, cut. The table on which the sausage or the the cut. In the;.time that-the table is movi" the table to the .width 'of a slice, and this adjustment takes the machine may -adjustedto all kinds of meat 'goods-'which must be cut thicker or thinner. The length of the to-and-fro movement of the table may also be r ulated to correspond tothesize' of the o ony to be sliced 1n order thatfthe travel o the table shall not be lar er than the Width of the piece of meat an no time be lost.

The cutting-machineaccording to this invention removes all't'he defectsl and drawbacks ofthe cuttin -machin'es hitherto known. In-jthese mac lines the-table isas a. rule fxedand the' 'knife adjustably irf ranged; also the lengths of cutting are measured too short,.so thatthe knife ress es more than cutaf This pressi-ng of s ices isl also caused'by the Wholewidth 'ofthe existing'knfe being in contact with the pieoe'of uot, i11varinb y' move-exactly in a' straightg line, and all hese mentioned drawbacks-tendping of the vknifeandthie cuttin'gof slices goods or Eeaoejfautomatically, and

ical or dished forni, so that only the knifeedge comes in contact with the piece of meat. The-circular knife revolves precisely in a straight line, so that disks or slices mathematically of equal thickness are cut o and slipping of the knife can no longer take place. A further advantage' is thatthe circular knife can be ground on the slicingmachine itself and also-that all sizes of meat polonies may be cut transversely or oblique y. Several, pieces may be sliced simultaneously on the saine machine up to the last ieee, which hitherto had always to be done y hand. f Figurel representsa'plan view of the device. Fig. 2 represents a front l view of the device. Fig. 3 represents a rear View of the device'. vF ig. ,4 represents a plan of a table arranged' obliquely-,to the circular knife. Figs. Wand. 3 are details of the' slicing-machine; Figs. 5, .5,and. 6 are respectivelyvertical crossi Section, longitudinal section, vand rear (eleva- `tion of the movabletable on an enlarged scale, showing also the mechanism for moving the polony andthe device for releasing so the same. i v' i lSimilalg'numerals of reference indicate` correspondi g parte in the figures.-

Referrin ,to lthe drawingsz-A table B for the polonies'or the like which are to be 85 sliced isa nged on a rectangular tablerame. A'in adove-t'ail groove or slide-track a by means of two v'slide-carriages b, movable in a transverse direction. At the .side in 'front of-the`table'a circular knife C is 9o mounted in a bearing frame or support c on the table-frame and with its cutting edge C as close as ossible to the front edge of the movable. ta le B.l The circular knife is inounted-on the endof a shaft c', which re- 95 volves on a cone-bearinge2 and has at its other vend a chain-Wheel F, Figs. l andl.

AThe shaft'c is also adjustable 1n the conebearings c2 'by means of set-screws c3. The rotation of the circular knife C and the movenient of the table'B up to andalong thev knife take `place from a main shaft D, l

-Whichl is arranged `in suitable bearings or supports-d d on the table-frame. 'As may beseenin Figs-,1, 2 and 3,-thie' main shaft 105 'is operated by a chain/K, carried over a .chain-wheel Ron theshaft if: of a handcra'nk E and over 'schein-Wheel R on the 'said main shaft D, the latter being placed too low to be directly m'ounted on the hand- 110 crank shaft. yOn the other end the main shaft l) carries a bevel-Wheel S, which en-` land arranged at right angles to the first w heel. One of these latter evel-wheels, S',

i produces the movement ofthe table B and the other, S2, the rotation of the circular knife C by means of the shaft' 8 of the latter bevel-wheel, which at the other end carries a large chain-wheel T', which by means of a chain L drives a smaller' chain-Wheel T on theshaft of the circular knife. The near Isupport.v Z for this end of thev-bevel-wheel shaft seis screwed to the table-frame. The

.speed of rotation of the circular knife is considerably increased by the adoption of a suitable ratio of 'transfer for the chainwheel gearing, and it is possible by the insertion of a larger `or smaller chain-wheel `rl" to vary the-speed according to requirements. By the spherical or dished form of the circular knife'the cutting edge C in cutting off a slice from thevpolony or the like will throw the piece cut off from the. latter into an open collecting-box or receiver E. 4This collecting-box is placed as close as possible to the movable table B and the revolving knife C. Its'forni is suited to that of the circular knife, and it is attached hot-h to the table-frame VA and also to the bearing frame or support 0.

As mentioned at the commencement of the specification, the circular knife may be ground on the slicing-machine itself. Its spherical form lends itself excellently to this, and for this object an emery-stone or the like is fixed on the table B and is then passed, with the moving table B, along the rapidly-rotating knife, thus sharpening the latter.

If, owing to repeated sharpenings the cutting edge c lies too far from the kfront edge of the table,` the table, wit-h vthe slidetracks a may be again moved closer up. For this object adpistable connections a for the slide-tracks a to the table-frame are employed, Figs. l and 2".

The transverse movement of the table B is effected in the following-manner: A pin e is adjustably mounted in'a slot e in theside of one bevel-wheel S., Figs. 3 and 3*.

.This pin engages in a slot g 1n a lever G which is revolubly mountedl in a table-frame underneath the bevel-wheelvand thel upper endv of which is pivotally connected, by means of a link H, with the under side of the table. The lever is thus ,osillat'ed by said pin e and imparts an alternating movement to the table. The movement outward of the pin e determines the length of the reciprocating movement of the table.` The position of the pivot g for the said vlever G is selected as regards that of the bevel-wheel S' in such a way that the leverage of the pin c on the forward movement is considerably larger than that onrthe return movement. The forward movement, that is to say, the

:one during which the knife cuts, is there! Ifore slower and the return movement, in which no work is. done, is rapidly effected. Fig.,3 shows in dotted lines the other endmost position of the table B, while the one shown-in Fig. 3, with the pin e in the slot e of the bevel-wheel S, corresponds to the greatest movement of the lever G. In case small slices are to be cut, for which the length of movement of the table only requires to be small, the pine is fixed in the other corner of the slot e in the bevelwheel to shorten the movement of the-table,

and in this manner no time is lost.

The surface of the table is ribbedor corrugated on the upper side toabout half its length, as show-nin Figs. 1 and 2, and the remaining part is covered with an' adjustable plate N, which is carried between dovetail bars h, arranged on thev side edges of the table.-` On the front edge of theplate N a clamp-for. the polony or the like is arranged., This consists of two .vertical toothed bears nn', whichare `eonnectedby means of a clamp-iron P,`,having a Vhandle p, Figs. 2 and 5. The one -toothed haraJ is fixed. The other n., thatis to-say, the one on the hand-crank side of the table, ispivot'ally connectedv with thecplate N and is always vpressed outward by means of a `sprin 71.2.', The clam -iron-P'has preferably apro le, whichpro ucesva` betterclamping ofthe vpolony or the like.

For cutting slices of meat the yadjustable plate N is drawn entirely back and the polony or piece of meat is clam-pcd thereon by the clamp-.ironPbeing engaged in one of the teeth of the toothed bar n., the handle p being then pressed down and allowed to spring into engagement with one of the teeth of the other toothed bar n. The clamp-iron ths holds the ypolony at` one end, with the other endl ing vatthe front edge of the table B. By t e` table being yprovided with sharp ridges .or corrugations and the knife, sov to speak, pressing down the.

polony while cutting it (it being moved by the movable table against the circular knife) `the polony cannot slip on the table althoughy i 'it is merely held `at the one end ofthe adjustable plate N.

As mentioned at the f commencement of the specification, after each cut, that is to say, on the return movement of the table, the polony or the like is automatically moved forward to the thickness of one slice. This adjustment iselfected in the following manner: A 4screwed rod V is'arranged in the centerline beneath the table B. Above this rod an elongated opening U is provided in the table, Figs. l and A nut is connected With the adjustable plate N, which nut con- 'sists ci' two parts, the upper one, t, of which opening n and is provided with arms, so as leased from the screwed bar V'.

is :tirrnly connected With 'the' plate N and' has nothread and thereforerslips over or along the bar V, while the lower part 'of the nut, t', which is hinged to the otherV part f, has, however, a thread, (see Fig. 5, which represents a vvertical cross-section of the table through nuts t zf).,v If then this part `he pressed against thescrewed,bar` V, this thread 'will engage with the thread thereon, and upon the rotation of the bar the plate'lil'will be moved forward. If, however, the threaded part 11" of 'the nut be released from the bar V, the plate N may be treelyadjusted or displaced.

The throwinginto engagement of the. nutf with the screw-bar V is ctt'ected in the fol-Q. lowing'. manner: The under part of the nut t is prolonged tq the one side, and this end Iig-slides in slotted bar fr, which extends along the entire extent of the elongated tn turn on pins e" r2 on the table, Figs. 5

and a, Tlike'a ball, which latter ligure represents a vertical longitudlnal sectlon of the table, the bar fr being in elevation, as seen from the right. @ne end arm the slotted liar is prolonged to the outside 'ofthe table ,and here formed into a counterweight W. A,In consequence of this counterweight WV the slotted bar i' is Valways raised, and there-f by the 'ander part of the nut is-pressed against the screwed rod. V,so that then the adjustable plate N is connected therewith.v however, the counterweightlV he raised, this connectlon will be released.

and the plate N may at once assume any desiredfposition on the table B. Withoutr'evolving the screwed-rod V. F ig. shows,

the polony or the like, is effected in the, following way by the backward movementoi" the table itself: On the end 'of this bar, outside the table, a ratchet-wheel fw is firmly mounted and elbow-levens zflloosely. n1 or mt ed th creen'. lever hears., hy' means ot' a roller z',- on an inclined planear cam f, which is yadjustably onnnected with the table-frame. On the other end e of the lever a pawl .e2 is pivotally `mounted to engage the ratchet lw, said pawl having a handle e toallow of its being disengaged. Y A second ro'ller 2 is mounton the ivot 'ot the pawl `to run on the,

table-trame as soon as the first roller 'L' has slices.

The one -endl e of the traveled oil' .the cam f, and any dropping down of the lever .-.arin is' thus prevented.

The inclinedplaneor cam is adjustable vertically and'horizontally, the screw-pin f., by which it isgfixed, being adjustable in ahorizontal elongated slot f2 in the tableframe and itself projecting through a vertical elongated slot f3 in the cam f and being vcrewed to the same by means of a nut,

i 6. f Y

)n the forward movement of the table the roller 'i runs down the inclined plane or cam and then the Aother roller 2 runs along the table. The, lever-arm e' then descends (and the pawl azuslides-over a number of teethof the stationary ratchet wheel fw. On the return movementof the table this leverarm, however, is again raised until the roller z' has reached the highest point'of the inclined yplane f, and the pawl z2 Iinthe rmeantime rotates the ratchet lwand there- Withthe vscrewed rod V,`so that lthe plate is pushed forward to the thickness of a slice kof meat. This operation is repeated at each `to-and-fro movement 'of the tn'ble, so that gradually the olony or the like is cut into By! p acing the cam f higher a greater displacement'I of ,the vplate' N; and thicker slices of meat may beobtained, while if a shorter transverse movement of the table at the bevel wheel S' is'to be obtained the cam or plane f must be corres ondingl",7 adjustedl to the right in the slot As hereinbefore mentioned, the polony or the like may also be clamped obliquely or wil cut, for instance, longenslices from a polony.- For this purpose an obliquetable B,I Fig. 4, may be utilized.v This arran e'- ment requires only another connection of ne n'utpn the plate N, namely,l by the upper part t of the nut being' formedlas a round pin or stud t to move between two bars or ridges o on the plate N." Thisarrangement 'is necessary when the screwed bar V is Vplaced at right angles, and gthe opening e must then be made'much broader. Fig. 4 shows these positions ofthe plate N in the' table B,-v allowing the .position of the nut between the bars o to be.clearly seenA4 The arrangement of the other parts requires, no alteration.
